TURBINE WATER-WHEEL.

SPECIFICATION forming part of Letters Patent No. 272,705, dated February 20, 1883.

Application filed November 6,1882. (No model.)

To all whom it may concern:

Beit known that I, BERNHARD KEISER, a citizen ot' the United States, of America, residing at Ferndale, in the county of Lehigh and State of Pennsylvania, have invented certain new and usetul Improvements in Turbine Water- Vheels; and I do hereby declare thefollowing to he a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which it appertains to make and use the saine, reference being had to the accompanying drawings, and to letters or tigures of reference marked thereon, which form a part of this specitication.

This invention relates to certainuiew and useful improvements in turbine water-wheels; and it consists more especiallyin theconstruction and arrangement of the. chutes or waterways, by whiclicoiistructioiiIam enabled tocontract and enlarge the same without changing the angleat which the water strikes the wheel, whereby the t'ull force ot' the water is utilized andanexpansible taperingpassageisprovided.

1n the annexed drawings, which illustrate my invention, Figure l is a longitudinal vertical section, and Fig. 2 is a horizontal section, showing the chutes or water-ways in different positions. Figs. 3, 1, and 5 are detailed views of the movable portions of the chute.

In the annexed drawings, A represents the lower casing, which is provided with a central shaft-bearing or step, which is held into place vand supported by a bridge which is located in the lower portion, as shown. The under portion of this casing is provided with an outwardly-extending ring or lange, A', to which the stationary and movable parts of thewaterways are bolted or otherwise attac-lied. The upper casing or deck, B, of the wheel is stationary in respect to the lower casing when they are united, and the horizontal extending portion B ot' this casing or deck is provided with a step, as shown at a, upon which rests a ring,C, to which are bolted the exterior portions of the movable chutes, so as to let on or out oi the water-supply when this ring is turned, which is done by suitable mechanical means, as a rack and pinion.

Between the upper and lower horizontal portions of the casi'ngs A and B are secured the stationary Water-guides D, and they are located between these casings, as shown in Fig. 2. These parts D are attached to the casings B and A by bolts which pass through the upper and lower casings and the eyes d d, thereby unit-iiigthe parts rigidly to each other; or, it' desirable, these portions ot' the chutes may be castings, so. as to form an integral part of the upper and lower casings. The inner end, c, of these stationary paits ot' the chutes are curved so as to be ofthe saine radii as the inner opening in which the wheel is located, and the outer sides,f, are curved so as to correspond with the outer radii of the casings, the vertical portion g of these chiites D tangentially located with respect to the periphery ofthe water-wheel. The inner sides ot' these parts ot' the chutes D are provided with sockets h, which are located near their inner ends, for the reception ot the movable portion or side ofthe Water-way.

The movable portions ot' the chute consist of two parts or castings, E and F, the part F being provided with an angular curved portion, F. The inner part ot' the chute E is plvoted within the socket IL b v the bolts t', which pass through the eyes j and the external casing. The stationary way E is provided with raised dovetailed projection 7c, as shown in Fig. 3, and the movable portion oi" this chute F is also provided with a dovetailed opening, bymeans of which the parts are united to each other, as shown in Fig. 5; thus allowing them to be expanded or contracted as the gates are opened or closed. The portion F of the chute F is curved on its outer portion, so as to extend over the curved portion F ofthe stationary portion oi the chute D, so as to be tlush with the saine. These portions F andf have corresponding curves. By these means I make the movable portion or one side ot" the chute expansihle longitudinally, and thus leave no break in the parts and retain the most desirable and eiective contguration-that is, a long tapering chute which opens directly upon the periphery of the wheel. The outer curved portions, F', of these chutes are bolted to the outer ring, C, and when it is turned it opens or closes the water-way, the .parts E and F sliding one upon the other. and being pivoted at the inner end ot' the watertway, the chutes always retain their wedge shape, and at all the hinged Way E, with dovetailed portion K, and corresponding dovetailed Way, F, with curved portion F', attached to the loperatingi5 ring U, substantially as described, and for the purpose set; forth.

In testimony whereof I affix my signature in presence of two witnesses.

BERNHARD KEISER.
